MARKER F03, PLANTERS.

Specification of Letters Patent.

Patented Aug. 10, 1920.

Application filed May 24, 1919. Serial No. 299,640.

To all whom it may concern:

Be it known that I, Orro H, Ko ipni ss, a citizen of the United States, and a resident of Caliunet, in the county of l-loughton and State of Michigan, haye invented a new and Improved Marker for Planters, of which the following is a full, clear, and exact description.

This invention relates to a marker, and I aim to provide a device of this nature more particularly adapted to be used in connection with a planter, such as a corn planter, the marker being adapted to be operated substantially simultaneously with the seeddroppingmechanism, so as to subsequently indicate the location. of the various hills.

My invention further aims to provide a device of this character which shall incorporate an extremely simple mechanism to provide for this operation and, in fact, a mechanism which might be applied to an old type of planter.

A further object of my invention is to provide a marker, together with operating mechanism therefor, which operating mechanism shall be actuated, together with the dropper mechanism, by a common operating means.

Another object of the invention is to construct a marker adapted to beused in connection with planters, which marker shall be provided with abaflie or a plow located forward of the marker to brush aside objects, such as clods, stones, and other debris, so as not to injure the marker; but in the event that through some unevenness in the ground the baiiie should fail to remove any object such as this, the marker is adapted to incorporate certain features of construction which will prevent its being injured, even although it should be projected at the instant when its end is directly above such object.

Reference is had to the accompanying drawings which illustrate one practical embodiment of my invention, and in which- Figure 1 is a plan view of the planter upon whichis mounted my improved form of marker in operative relation to the various parts;

Fig. 2 is an enlarged side elevation illustrating the specific construction of the marker, together with certain actuating parts of the dropper mechanism;

struction for planters, there is mounted upon the axle 7 a bevel-gear wheel 8 which meshes with a corresponding gear 9 slidably mounted upon a rotatable shaft mount ed upon and extending between the crossbars 3 and at. The gear'8 is formed with an integral collar 11,.which may be engaged by any suitable shifting lever such w taken along as 12, as clearly shown in Fig. l of the drawings.

Secured to the front end of the shaft 10 is a disk 13 provided with an inclined shouldered member 1a. Hoppers 1,5, adapt ed to receive seeds, are preferably arranged oneach side of the sills 1 and are provided with seed-dropping mechanism (not shown), which seed-dropping mechanism is operated by the oscillation of a bar 16. Secured to the shaft 16 is a stirrup 17 carrying upon its outer end a roller '18, which roller is adapted upon rotation of the disk 13 to be engaged by the incline 14, consequently rocking the bar 16, and is adapted to be released, upon further rotation of the disk 13,

from engagement with the incline 14 by virtueof the latters shoulder.

It will be seen that by the above I have converted the rotary motion of the disk-13 into an oscillating motion of the rod 16. v

The function now to be fulfilled is to cause reciprocation of the marker 19, and to accomplish this I secure to the pulley end 18 of the stirrup 17 one end of a flexible cable 20. An inclined block 21 is mounted upon 32 and the base 36, is a spring 38.

pole of planter, and secured to such block and extending outwardly therefrom at an angle of approximately 45 is a pulley 23 around which the cable 20 is adapted to pass. A standard 24 is secured by any suitable means to the pole and supports two pulleys 25 and 26 at its base and top respectively, the cable 20 passing around such pulleys 25 and 26 and having its other end secured to a lever 27 pivoted to the pole, as indicated at 28, one of the arms 29 of such lever having its end portion bent upwardly at right angles to its body part. The opposite arm 30 extends upwardly from the pivot point 28 and terminates in the form of a cup 31.

The marker 19 includes a head 32 the base of which is encircled. by the upper end of a cylindrical sleeve 33, as indicated at 34, such sleeve 33 being provided with a pair 'of longitudinal slots 35 for a purpose hereinafter more fully described. A base portion 36 provided with outwardly extending pins 37, adapted to move within the slot 35, is encircled by the lower portion of the sleeve 33; and positioned within such sleeve 33, and interposed between the ends of the healgll squared body 39 maybe attached to the base 36, and secured to the lowermost portion of said squared body is a foot 40 which may take the shape of a slide 41, as indicated in Fig. 4. A bracket 42 is secured to the outer face of the pole, such bracket comprising a main portion 43 through which the markers base 36 is adapted to pass. 'An additional bracket is secured to the main bracket 42 and is formed with a squared opening through which is adapted to project the body portion 39. An annular groove 45 is cut in the outer face of the head 32 and is adapted to have mounted therein by means of a locking washer 46 a spring end-plate 47, a spring 48 being adapted, to encircle the marker and to extend between the spring end-plate 47 and the upper face of the bracket 42.

A bafiie or plow 49 is suspended from the pole by means of straps 50, but I wish it understood that this construction may be 7 eliminated entirely if it is so desired.

In operation it will now be seen that if the lever 12 is moved forwardly so as to permit engagement between the gears 8 and 9 with the shaft 10, the disk 13 will be rotated- The inclined shouldered member 14, integral with or secured to such disk 13, will engage the roller 18 and cause the same to move inwardly, rocking such roller about the shaft 16 to which it is secured by means of the stirrup 17; and in view of the fact that the shaft 16 has the end of the stirrup 17 rigidly secured to it, it will cause such shaft 16 to oscillate. The cable 20 will be pulled every time the roller 8 moves inwardly, by reason of the fact that one end of the cable 20 is secured adjacent to such roller. This pull will cause the lever 27 to be rocked around its pivot 28 and, consequently, the lever 30 together with its cup 31 will be depressed. The cup 31 engaging the head 32 of the marker will force the same downwardly and result in the foot 40 coming in contact with the ground almost simultaneously with the dropping of the seeds from out of the hopper 15, by actuating means operated by the shaft 16.

Should now the plow, or baflie 49, fail to remove some object from out of the path of the foot 40, and the foot should engage only a hard object upon being depressed, the base 36 will ride upwardly within the cylindrical casing 33, by reason of the pins 37, against the tension of thespring- 38. This will effectually prevent any breakage of the foot 40. Further, it will be noted that by virtue of the squared shoulder 39 any turning of the marker of its own initiative is prevented.

Havingthus described-my invention, I claim as new and desire to secure'by Letters Patent:

2. A marker adapted for use in connection with a planter, including a driven disk provided with an inclined shouldered portion, a rod for actuating the conventional seed droppers used in connection with such planter, a lever having one of its ends se cured to such rod and being provided at its opposite'end with a roller adapted tobe engaged by the inclined shouldered portion, a marker secured to such planter, a lever adapted to depress such marker, and a flexible cable having one of its ends secured to' the inner end of the lever, the opposite end of such cable being adapted to be secured to the first-named lever at its roller end.
